Permatex 81833 Heavy Duty Rubberized Undercoating, 16 oz. net Aerosol Can

The spray head of this can is downward, and the sprayed liquid will spray on the body of the can, and the spray is uneven, which is not easy to use. Ionly open one can, and the unuesed ones cannot be returned

It works great. Sun will not cause it to crack. Will last forever after you spray your gutters. Sure there may be a million other uses but gutters is good one.

I'm quite impressed with this, enough so to follow this can with a case of 12. Goes on marginally prepared surfaces quite well and has a nice sheen to it. Goes right where you aim it and no overspray to speak of. Dries well and relatively quick. I sprayed the trunk of my 1947 Ford as well as under the fenders after basically just vacuuming the surfaces and wiping obvious messes up. I will try to update this after some months have passed of usage.

Very good products

Works well, used on asphalt roof to patch roof leak
